摘要(Abstract):

岩爆是地下工程的一大地质灾害,目前还没有成熟的预报和治理方法。利用爆破手段释放高地应力来减少岩爆,一直是地下工程施工研究的重要课题。在锦屏二级水电站2#引水隧洞,进行了爆破释放应力试验,分别试验了掌子面倾斜辐射孔和围岩内倾斜辐射孔两种方案。试验结果证明了爆破是高应力释放的有效手段,通过合理的爆破设计与施工,可以达到控制或缓解岩爆的目的。
Rock burst is a big geological disaster for underground engineering without preferable forecasting and solving means at present.Releasing high crustal stress by blasting means to decrease rock burst is always an important task for underground engineering construction.In 2# diversion tunnel at Jinping two-stage Power Station,stress release-blasting experiments(declining radiating holes at working face and adjoining rocks) were carried out.The experimentation proved that blasting was an effective means for stress release,by reasonable blasting design and construction,the result of controlling or decreasing rock burst could be achieved.
